Everyone around the world is welcome to participate, from newbies to professional game developers—and your game can be as simple or complex as you want. It’s a great excuse to learn a new technology, collaborate on something over the weekends with friends, or create a game for the first time!

Create a new public GitHub repository to store the source code and any assets you’re able to share for your entry and push your changes before December 1 13:37 PDT.

Submit your game through itch.io.

You can participate by yourself or as a team. Multiple submissions are fine. And of course, the use of open source software is encouraged.

Voting

Voting will open shortly after the jam ends and is open to everyone who’s submitted a game. Similar to last year, entries will be rated on the following categories: Overall, Gameplay, Graphics, Audio, Innovation and Theme Interpretation.

As always, we'll highlight some of our favorites games on the GitHub Blog, and the world will get to enjoy (and maybe even contribute to or learn from) your creations.

Help—I’ve never created a game before!

With so many free, open source game engines and tutorials available online, there’s never been an easier (or more exciting!) time to try out game development.
